I tried to grow orchids using a peat perlite mix instead of orchid bark. I water it less often and my plants grow better than before. They thrived and I start growing some of my Oncidiums, Miniature Cattleyas, Cattleyas and Dendrobiums in a straight peat medium. Though I am successful, I was worried because I haven't heard any recommended peat mixes for orchids. Later I found Professor Yin-Tung Wang of Texas had studied Phalaenophis grown in peat-mixes and confirmed peat's effectiveness. We can consider peat based orchid medium because it is easy to say when to water, watering is easier and you can use water less often, peat keeps your orchid evenly moist and helps your orchid feed. It is easy to repot orchids growing in peat and to prepare fresh peat mix to use. So that’s it. If you’re a home grower, and you want to grow healthy orchid plants with less work, you should give peat a try. Click
